more power to you - don't take this the wrong way, but I went through my tie everything to see what works phase 30 years ago. After figuring out what works (more importantly how to fish it), I've culled my fly patterns to a handful, 3 for warm(fresh)water, 3 for salt, and maybe 6 for coldwater.
I have friends who tie flies for fun and relaxation, and have stacks of fly boxes they'll never open again. I tie hand-to-mouth, only when necessary, and then begrudgingly.
speaking of soft hackle, pheasant rump soft hackle on my kicking shrimp - my go-to salt fly
size 6 standard length stainless, kevlar thread
stainless bead chain
the body - legs of the shrimp - is palmered rooster hackle
the wing - kicking shrimp tail - is 2 pheasant crest feathers.
it really looks weird in the vise
and has served me without fail those 30 years
second cast of the morning in the back of Allyn's lake - first cast was a larger spec that tore the hook out on her second run
oddly, I've caught kings at the jetty on this fly - an activity guaranteed to wear you out
I spent 10 years working on kicking shrimp ideas, since stripping a fly line is a natural imitation.
Some of my creations worked, but when I saw Ally's shrimp salmon fly, I knew what to do.
The bead chain clicks - nothing looks more like shell than soft hackle, and it slowly flutters down like a spoon.
No reason to go any further for crustacean-food-thingy imitation.
Something else you don't see in the wrapped pheasant rump soft hackle - it's loaded wit iridescent red, green and blue and all that color collapses back together in the water.
Good fly shops, which don't really exist anymore, would give away the pheasant rump that came with the tail feathers.
For awhile, you could buy the whole pheasant skin minus the tail feathers for $3 - now they're about $15.
With the skin, there are some better wing (shrimp tail) feathers at the base of the crest.
